Introduction. It terms of topographic and anatomical approach to the problems of embryogenesis has done with help of proper morphological methods The research of morphogenesis and dynamics of space-time relationships of pelvic joints during the fetal period of development. Vertebral arches are laid before its vertebral bodies but they exist separately for a long period of time. After the development of pre-cartilage tissue begins in the spine, intervertebral cartilages (future intervertebral discs) appear in the form of thin strips of compacted mesenchyme. They begin to form in the cranial spine of embryos 10.0-13.0 mm parietal-coccygeal length (PCL) and are found along the spinal column.
